"To all whom it may concern:; .1

Be it known that I, EDWARD P. SHELDON, a citizen of the United States, residing at New York, county of Kings, and-State of New York, have mvented certain new and useful Improvements in Delivery Mechanism for Folded Products, fully described and represented in the following specification and the.accompanying'drawmgs, formin apart of the same.

. hisinyentionrelutes to im rovements in usually secured together by; stapling or machines: for-producin a 01 ed product.

Inproducmgfolde products, such, for instance, as weekly, pa ers, or magazines comprising a.- large ham "or: of iesconstitut ng'what may be termed a single signature, it is customary either to apply the cover and the inset advertising sheets, when they are" used, inothe printingmachme by agencies connected directly with the printing machine, in which case the'product is otherwise by agencies forming a part of the printing machine, or the main part of the product is produced in the printing machine and the inset sheet and cover orboth are a applied after the product is taken from the printin machine, in which case the securing of the p ies together isefi'ected outside of the printing machine. Further, in the production of the products referred to, it is customary, after the product .is completed, to trim the ends and sides of the product, this being accomplished by an independent trimming machine.

It is one of the objects of this invention to produce an improved machine for producing a' folded product provided with a delivery mechanism which includes devices by which the product may be trimmed, and

a second delivery mechanism which receives 'the product in an untrimmed condition, the

iechanism including means by which either elivery mechanism may be utilized,

A further object of the invention is to pro- ;duce an improved trimming mechanism which may be employed in connection with machines for producing a folded product, sitidmechnnism embodying devices by which tiheedge of the product opposite the fold line twee trimmed.

iitiduce a trimming mechanism which may I l u e u a oegemploycd 1n connection with a machine 5 orfproducing a folded product, said mechaurthcr object of the invention is to nism including devices for trimming the endsof the product and the edge of the product opposlte'the fold line, there being: also employed means for presenting the product successively to said trimming dc- V1085.

With these and other objects not specifically referred to in view, the invention conslsts in certain constructions and in certain parts, improvements and combinations as will be hereinafter fully described and then specifically pointed on Referring to the drawings -l igurc 1 is an end view, partly in section. of one form of mechanism embodying the invention, this mechanism being shown in connection with the product assembling mechanism of a fast rotary. printin machine. Fig. 2 is an end elevation, part y in section, of the construction shown in Fig. 1, the product assembling mechanism of the printing machine being omitted from thisview. big. 3 is a detail sectional view illustrating more particularly. the edge trimmin devices and the parts immediatelyconnecte therewith. Fig. 4 is a view similar to Fig. 3 but showing some of the parts in a different position. Fig. 5 is a plan view of the construction illustrated in Fig. 3.

Constructions embodying the invention are particularly adapted for use with the product assembling devices of fast rotary rinting machines, although as to all its eatures the invention is not restricted to such use.

In the particular construction illustrated, 1 indicate the drawingpll' rolls ordinarily employed in a printing machine for ussemblinganulnber of printed webs. From these drawing ofl" rolls, the webs, in the construotion illustrated, pass between the usual cutting cylinders 2 by which the webs are ditill lLO

ing between the rolls (3 by means of rolls 7 and a roll 7. v

The particular machine illustrated is also provided with means for securing together the various plies which form the product. As shown, the plies are secured together by staples which are inserted by a stapling roll 8 coiiperating with one of the rolls 7 before referred to.

As illustrated, the product after leaving the rolls 7, 8 passes in a flat form between rolls 9, and is forwarded by tapes 10 passing around the rolls 9 and 11 beneath a transverse folding knife, as indicated at12.

It Will be understood that the devices so far described are of usual form, and that other devices may be substituted for some or all of them, if desired, those illustrated being selected merely to illustrate a form' of mechanism for producing a folded product.

When the invention is carried into effect in connection with a mechanism for 'producing a folded product, the product may be forwarded from the folding mechanisn ito a delivery mechanism including trim; ming devices. In the particular machine shown, the transverse folding knife before referred to passes the product into the nip of a pair of folding rolls 15 Whichrolls deliver the product to a guide 14 which in turn directs the product to a set of forwarding tapes 15, 16. The tapes 15 pass around supporting rolls or pulleys 1'7, 18, 19, 20, 21 and 22, and the tapes 16 pass around rolls orpulleys 23, 24, 25, 26, the pulley 19 before referred to and a roll 27. These tapes constitute a well-known type of forwarding device for the product, but it is to be understood that any other suitable form of forwarding device may be used instead of them.

In the particular machine shown, the i591- warding devices conduct the product past suitable trimming mechanism which operates to trim the ends of the product. \Vhile this trimming mechanism may be Varied iii character, as shown, it consists of rotary slitting knives 28 which cooperate with the roll 19 before referredito. This roll 19 may be a driven roll, and in the construction illustrated shown as drii'en by an intermediate 29 from a gear 30, this gear being in mesh with a' gear 31 on a shaft 32. This shaft 3:2 when employed may be driven in any suitable manner. As illustrated, it is provided with a gear :33 in mesh with a gear 31 on a shaft 155 this shaft being driven from a way shaft 236 by means of the usual bevel gears 37, 38. The shaft 36 may be driven from a Shaft I59 which may constitute the power shaft of'thc mechanism, by means of iutcruacshing gears 40, 41.

lVhcn the invention is embodied in a machine which includes end trimming devices, the product may, after it has been acted upon by these devices, be subjected to the action. of mechanism by which the trimming of the edge of the product opposite the folded edge is effected. The edge trimming mechanism employed may be varied widely. As illustrated, the

product, after passing between the tapes ble upon which the product is brought to a .s'top before trimming, the registering device may include a series'of swinging stops 50, these stops being mounted on a rock shaft 51 which may be operated through a rock arm and a rod 53, this rod being actuated by a cam 54 on a stud 55, the cam being driven from a gear 56 in mesh with a gear 57 on the shaft 32; IItWlll be .understood, of course, that by the mechanism re ferred to the stops" will be interposedin the path of the product at the proper time to stop it, so that the edge to be trimmed will vices,

The trimming devices, in the particular machine illustrated, include a knife 58 secured/by a screw 59, or in any other suitable mann'er,to a cross-head 60 arranged to move in ways 60', the knife being, if desired, adjusted by a set screw 61, or in any other suitable manner. As shown, the knife cooperates with a'cutter block 62 mounted on a cross bar 63, this bar also serving to support the table 48 before referred to.' When a cutter of the-character be properly presented to the trimming 'de referred to is employed, the cutter head which carries it may be operated ;-in any suitable manner, In the particular construction illustrated, thei'cutter head is operated by' means of rods 64-,"these rods carrying studs 65 which work in cam grooves 66 in cam disks 6?, these disks beingnionnted on a shaft68. lThissha'ft 68 may be driven in any suitable manner, as by an intermediate 69 and a gear 70 from the. gear 56 before 'referred to.

The plies of freshly folded products do not, as ar u'le, lie flat andt here is often considerable air between the plies, so that should the product be trimmed at the/edge opposite the fold line without flattening down the plies andeizpelling thetir, the

edges of the plies'would behable, tobe uneven when the product issubsequently flattened out. and the air expelled. Machines embodying the invention in its best forms therefore, will include means for compress ing the plies and expelling the air prior to the trimming o 'ieration.

While these means may be varied, in the particular construction illustrated there provincial a frame 71 forming three sides of a rectangle, this frame being; of a size to press upon ihe margins of the folded prod-- uct so as to flatten it and expel the air without pressing upon the printed part of the prmluct, thus avoiding offset. The air expelling; ihrame, in the particular machine illustrated, is pivotal'ly supported on a rock shaft 72 inv turn supported in I rackets 73. in the construction illustrated, these braclc ets are mounted on a bar Tel. which will be hereinafter referred to. In the best conslruetion, this air expelling frame, when a. :lt'ranie is employed, for this purpose, Will standso that that edge 'WlllCll operates upon the fold of the product will come into op eration first. In the machine shown, this is elfected by n'iounting the :frame so that that part of it which operates on the product near the fold line is nearer the table 48 than the remainder of the frame. To maintain the iframe in proper position, it may be provided With heels 75 Whiclrbutt against the (bar 74, To maintain the frame firmly and yet yiveldingiy in position, so that itmay exercise a proper pressure upon thev folded product, the shaft 7 2 on which the frame is mounted is,'in the machine illustrated, provided Withlan arm 7 6 to which is connected a spring rod 77 surrounded by a push spring 78 which bears against a bracket 79 fast on the cutterohead through, which bracket the rod 77 plays. In the o eration of the device,,as the CITlJlZBI' head ceseends, the too or end of the frame farthest from the cutter head strikes the fold of the product first. As the head continues to descend, the frame comes into operation .along its sides, thus flattening the product and ekpelling the air therefrom. v

in the best constructions embodying the invention a clamp will be employed for the purpose of firmly holdingg theeclge to be trimmed during the trimming. operation. While this clam may beicoristructed in Various Ways, as siown the bar 74: before referred to is utilizedfor this purpose. this bar being carried by spring plunger-s 80 soclrcted in the cutter head, this construction being a usual one. After the frame has flattened out the product and expelled the air, the bar 7 clamps the edge of the product after which the knife comes into operation and trims 'he edge.

il'i hen the edge trimming means employed is of such a character that the product stopped in order to effect the trimming, means may brprovided for again forwarding the product after trimming. While the ans em lo ed ma be varied in character as shown, there is provided a series of for warding rolls 81 mounted on a shaft 82, this shaft being preferably continuously driven in any suitable manner, as, for instance, by a gear 83 loosely mounted on the shaft 51 before referred to, this gear being in turn driven from suitable gearing on shafts 8% which carry. in the machine illustrated, directing rolls 84'. A guide 85 may be employed in connection with these diri'ectingi, rolls. There is employed, in the machine shown, in connection with the rolls 8i, drop P011586, one of these drop rolls and its carrying arm being: shown in Figs. 3 and 5 of the drawing, these rolls being mounted in arms 8? extending from a rock shaft 88, this shaft being provided with an operating arm 8 to which is secured a rod- 90, this red being driven from a cam 91 on the shaft 68 before referred to. The product ha ving been trimmed andset in motion may be delivered in any suitable manner. In the construction shown, the rolls 84 deliver to the usual S-fly 92 which in turn drops it on a conveyec93 of the usual type.

It may be desirable to deliver the folded product Without trimming. Machines embodying the invention will, therefore, include a second delivery mechanism which does not embody trimming devices. In the construction illustrated, the guide 14; is formed as a switch and may be set so that the product coming from the rolls 13 instead of being delivered to the advancing devices before described, may be delivered directly to unSsfly 9% which in turn delivers the productitoi the conveyor 93.

Changes-and variations maybe made in the construction by which the invention is carried into effect. The invention is not, llllGX'G'flJI}, to be confined to the particular constructions herein shown and described.
